The ens A, A, F, F, and K, K, with pipes D, and Lform the frame of thedevice and the pipe B which is a part of the frame also forms the axleof the device, such frame being reinforced or strengthened, whendesired, by the couplings e, e, Z, Z, and the brace pipesY (or rods) E,E, and Z', Z'.

M, M, are the supporting, carrying and actuating wheels of the deviceand are provided with a hub which turns freely on the axle B, and withspokes m, m. l N is the carrying and mixing receptacle of the device.Receptacle N is loosely mounted on the axle B.

O is a recess or socket in pipe L of the frame of the device. L

P is a bolt longitudinally movable in bearings p, p. Bearings p, p, arerigidly attached to one end of the receptacle N as by rivets or boltsp',.p'.

P' is the handle by` means of which bolt.

P is moved.

P is a dog arranged to alternately enga e with recesses P'", P'", onbolt P.

is a spring arrange/d to yieldingly Q is a plate rigidly secured tospokes m, m, of wheel M as by straps g, g, and g', g', are recesses inplate Q arranged to form sockets for the 'bolt P. f

The receptacle N is locked so as to rotate when the bolt is in socket Oin the lframe of the device; and is locked to wheel -M to rotatetherewith when such bolt P is in any one of the sockets g', g on disk Q.

The receptacle N is provi with an aperture through which 1t may beloaded and unloaded and R, R', are doors arranged to form the cover tosuch apertures. To hold the doors R, R', closed, the ends t, t, oflevers T, T, are arranged to engage with abutments 7', r', on such door.Such abutments have rollers thereon shown in the drawings. Lever T isloosely. mounted on Eile B, such axle passing through the hole t' S, S,are stops secured to one end' of the receptacle N, arranged to limit themovement "of the handle t.

The lever T`which is located at one end of the receptacle N is attachedto the like lever T at the other end of the receptacle by the beam orrod T so that the abutments r, r', at both ends of the doors R, R', arelatched bythe said levers T, T, andimlatched when force is applied tothe lever' at one end of the receptacle.

The operation of the device is ;-When a suitable quantity of cement,sand and broken stone has been put into receptacle N and the doors R,R', locked in a closed position, with the bolt P moved to engage withone of the recesses g' on disk Q, as the device is hauled along theground the receptacle N is rotated simultaneously with the wheels M. Bydriving the vehicle along the ground at such time, (with valves 1, I,closed), the contents of the receptacle become well mixed while in a drycondition. Assuming the tank G to contain the proper quantity of waterto wet or moisten the contents of receptacle N, after the desired drymixture of the contents of such receptacle has been obtained, the valvesI, I, are opened and the vehicleis driven a farther distance'along theground and until a wet or moistened mixture is obtained.' When athoroughly mixed and moistened mixture o f the contents of thereceptacle N is obtained the device is driven to the placewhere thecontents are to be used and the receptacle placed in the position Ythereof illustrated in Fig. 3 of the drawings. When the rece tacle is inthis position the contents thereof rest on the doors R, R', and thehandle t" of lever T is in position so that a person standing at therear of the vehicle may force such handle down thereby turning saidlevers T, T, and drawing the end t of the levers out of engagement withthe abutments r, frl The contents of the tank will then force the doorsopen and such contents will fall out of the receptacle to'rest on theground'. The vehicle is then driven or drawn forward and the rear door,being prevented by stop U from opening beyond a given distance willscrape over the unloaded contents of the receptacle so that the edge uof such door will tend to level the load.

The board V is attached tothe inner .side

of the wall of the receptacle N by bolts a',

e', and the ballie plate W is secured to the receptacle is acceleratedby such contents being carried up by board V and discharged ,on thebaffle plate W as the vhicle is belr driven forward and the receptacleis`lock to the wheels M to turn therewith.

vThe ends 0I' the pipes C, C, which ,are in f' l the ells A, A, and theends of pipes E, E, inl l couplin e; are or may be closed.

A su cient quantity `ofwateris putjinto tank G to properly meisten orwet the mix- Y ture obtained in ythe receptacle so that a.

properly moistened mixture. is easily ob# tained. Y v

1 do not confine myself to the use of. pipes or tubes in building)theframe" of the device, other than pipes ,"D, and-pi Ae B with nipplesH,'H,`which are re uire to conve the water from tank G to t e rece taclewhile the device is lbeing hauled ong the ground and the contents of thereceptacle are being thoroughly mixed, as described.
